"BENEFICIATION OF HIGH-MgO SEDIMENTARY

Dolomite [CaMg(CO3)2] is an intolerable impurity in phosphate ores due to its MgO content. Traditionally, the Florida phosphate industry has avoided mining high-MgO phosphate reserves due to the lack of an economically viable process for removal of dolomite. However, as the high grade phosphate reserves become depleted, more emphasis is being put on the development of a cost effective method

Sedimentary and Igneous Phosphate Deposits:

This element, also critical in a host of industrial applications, is a nonrenewable resource that is sourced primarily from the phosphatic mineral apatite, hosted in sedimentary and igneous ores. World phosphate resources are estimated by the U.S. Geological Survey at ca. 300,000 Mt, of which 95% are sedimentary and 5% are igneous.

Phosphate ores in terms of quality and P 2 O 5 grade can be divided into three groups: low grade ores (12–16% P 2 O 5 ), intermediate-grade ores (17–25% P 2 O 5 ), and high-grade
